It's my 'workout' mp3 player (actually my only one, but that's all I use it for) - it's small, light, cheap & gets the job done. I'm not that bothered about sound quality - it seems fine to me. I think there *may* be a 'increase volume' option somewhere as there was with a previous Sansa mp3 player I had.

Works both with Linux & Windows - can plug it in & it's recognised as removable device. Also, you can create your own playlists (m3u files) under either OS & have them appear in addition to the 'Go list' - useful if you have some tracks that you have to listen to in a specific order (i.e. live albums, etc).

Once complaint is that outside (in the sun) it can be extremely difficult to see the display. Which makes it hard to switch tracks, etc, while running. Aside from that, I love it. I use my own (el cheapo) headphones, so can't comment on the quality of the included ones..
